Hi Eegoos,
Welcome to Sony Community!
Thank you for your message. We can't guarantee if Samsung Evo+ SDXC 128GB will work to the Max Speed with this laptop.
We highly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/ to assist you with this issue.
Regards,
Jen
